Bee Balm

DAYS TO GERMINATION: 7-14 days at 60-70°F (16-21°C).

SOWING: Transplant (recommended): Sow the seeds in flats, barely covering them. Transplant to individual containers when the seedlings have their first true leaves. Transplant outside in the spring or summer, 6-8 weeks after starting the seeds, spacing plants 8-12" apart. Direct seed: Sow from early spring up until 8 weeks before the first frost in the fall. Direct seed or sow in a cold frame to be transplanted when they reach a height of 3-4". Sow about one seed per inch in rows 18" apart. Thin to 8-12" apart.

DISEASE: Bee balm is very susceptible to powdery mildew, which is exacerbated by humidity and any kind of plant stress, even drought. To reduce the tendency to mildew, keep the soil moist, minimizing overhead watering; space the plants far enough apart to allow for good air circulation between plants; remove diseased foliage to prevent the fungus from overwintering; and divide the plant every three years or so, discarding the old center growth and replanting the new side shoots.

HARVEST: Starting the first year, leaves may be harvested. More leaves may be harvested each year as plant size increases. Bee balm does not usually flower until the second year. Mature plants, 3-4 years old, can be divided to make new plants.
